Proteins synthesis requires transcription of DNA (containing information) to mRNA then this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together with ribosome and tRNA to synthesize proteins. Further steps are the following: 1) One side of DNA strand is copied to become mRNA (messenger RNA). 2) mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome. 3) mRNA works with ribosome’s 3 bases at the same time. 4) tRNA (transfer RNA) connects with available DNA bases. <span>5) tRNA releases the amino acids which in turn combines with the other produced amino acid chains from different DNAs. </span>
Upper mantle, lower mantle. idk the third
To properly build the phylogenetic tree, Julia needs information that can connect any of mentioned mammals (bear and monkey) to reptiles. And that could be only the fact that a duckbilled platypus lays eggs similarly like reptiles. So, the platypus is a mammal and relationship with bear and monkey in that way exist, but laying eggs is not characteristic for other mammals.
